\ STEAM-ENGINE.

Application tied June 1c, i913. serial iig. 774,036.

T0 all 'whom t may] concern.' y

y Be it known thatfI, `ELZA R. Dicker, citiat Dug` zen of theUnited States, residing ger, in the county of Sullivan"and State of Indiana, have invented certain :new and usey ful Improvements in. Stearn-4 Engines, of which the following is a specification.

This invention relates to an; improvement in steam engines.

l The primary object of theiinvention is to so construct a` reciprocating steam engine that major portion ofthe 1pressure and eX- pensive force of the steam will be utilized to` generate power. y

A further `object ofthe invention is te` will be reduced to a minimum, and in which the movable parts will be so supported that `undue wear will be avoided.

A still further object ofthe invention to provide means for supplyingLsteam-and taking the exhaust 'from a reciprocating cylinder, whereby the cylinder may be moved freely without danger of leakage of the steam when supplied to the cylinder or removed therefrom.

For a full understanding of the invention, reference is to be hadto the following description and accompanying drawings, in which Figure 1 is a side elevation; Fig. 2 is a top plan view; Fig. 3 is a longitudinal section of the cylinder and steam chest; and Fig. 4 is a section taken on `the line 1f-4 of Fig. 3.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

In the drawings, 10 designates the engine base or bed. This base consists of the frame l1 and a transverse web 12,the upper edge i vof the web being concave to accommodate l and aid in supporting the engine cylinder as shown at 13. The side members 14 of the frame 11 are provided at their upper i i edges with a flange 15 to which are bolted plates 1G which overlie the bed-plate. These plates are secured to the flangel by bolts y 16, the bolts passing through elongated slots in the plates, whereby the plates may be y moved laterally.

A cylinderl? rests upon the web 12 and is disposed to slide in the concave top edge 134 thereof, and is provided at eachof its sides with spaced ribs 18 between which the plates Specification of Lettersilatenti provide a construction .in which friction Patented oct. e, i914..

cylinder which may be conveniently` lubricated. Acrank shaft 19 is mounted in 1bear-` ings 20 at theend of the base remote from the cylinder.` The shaft 19is` provided with nected to the yoke 22 of apiston rod 23, and the cranks 24 being disposed` on both sides to said crank 21. 4

1 The cylinder 17 Rods 27 connect these trunnions respec-` tively with the cranks 2st at ,the` same side struction thatwlien `the piston rod `23de ingguided in lits ,movement by the plates movement.` l i y. l A steam chest 2S 1s mounted on the cyl`- being controlled by the valve rod 29` which base 10, and are adjustably `connected to the converting rod 32 actuated by thegeccentric 33 mounted on the crank shaft 19. A cylindrical steam drum 34 is mounted on the steam` chest 2S,` the steam chest,` being provided with an `opening 35 which comis of a length sufficient to allow for the full stroke of the cylinder.

a packing gland 37.

.A steam pipe `3S extends through one 39 intermediate its ends. 40 is connected to the steam chest, said pipe is mounted to reciprocate in `an exhaust drum .42, the drum being provided witha gland 43 at its end which receives the pipe 411-.

when the cylinder reciprocates, the steam drum 34 will slide on the steam supply pipe 88, the supply of steam to the cylinder bevalve gear is such as to permit of the reciprocation` of the steam chest "and,fat the same time, allow for the proper feeding of three cranks, the central crank 21 beingconl of the crank`21 and in an opposite direction` of the bed. It will be `noted, by this con.-`

rcciprocated, and the crank shaft 19 is ro?` tated, the cylinder will. be reciprocated, be-

16` and effectually supported against lateral;

inder, the-supply of steam to the cylinder The drum` at `each.` end is closed by a plate 36 which supports gland 37 and supplies steam to the drum, the pipe being provided with perforations` An exhaust pipe being provided with an extension 41 which It will be noted by this construction that `16 entendpthereby forming guides for the l y y adjacent its frontend 1, 2o is provided on each side with trunnions coiinected toa yoke 30. Thearnis V31 4 ofthe yokeBO extend' on both sides ofthe municates with the drum. `The drum is disposed to move with the steam chest, and` ioo int COHI'Oed in the usual manner. The 1 110g the steam to the cylinder.y As vthe cylinderl reciprocates, the exhaust pipe will telesco-pe in the exhaust drum and the inlet and 'outlet of the steam thus accommodates itself to the reciprocation of the cylinder. 'Theu manyadvantages .of a constructionofhthis character will be elearly apparent, as it will be seen that the larger portion of the pressure and expansion of the steam isA utilized, and thatgreater power will be gen-` erated fromr a fcertain steam supply than would be generated 'if the cylinder lwere stationary.

Particular attention vis called to the vpeculiar manner of mounting Ithe cylinder, as well as the means for supplying and eX- hausting the steam fromthe same. By this construction, friction is reduced '5to a mini/- mum as the movable parts are 'so mounted;

f that `undue wear -is prevented. It will also be seen that the entire structure -issuch as may be easily and economically manufactured, and that the various parts may be readily assembled, it being noted that the device may be used with all fluid pressure motors.

Vhat I claim is:

l. A steam engine comprising, a cylinder, means to reciprocate the same, a steam chest mounted rigidly on the cylinder, a barrel carried by and movable wit-h the steam chestl and .communicating therewith, a steam supin presence of two witnesses.

rslide on said pipe, a slide-valve arranged in the steam chest and operable by the means for .reciprocating the cylinder, and an exhaust pipe communicating with the steam chest and movable with the cylinder.

' 2. A steam engine comprising, a cylinder, a piston arranged within the cylinder,

.means for simultaneously 'reciprocating' 'the piston and the Cylinder, 'a steam chest mounted on and movable with the cylinder,

la barrel carried by and movablepwiththe 4steam chest and communicating therewith,

:a stationary `steam supply pipe extending through the barrel and provided interme- Idiate itsends with a series of perforations', a slide-valve arranged inthe steam chest, means whereby the valve will be 'reciprocated simultaneously with the piston and the cylinder, an exhaust pipe connected with ithe steam chest, and a barrel in which said exhaust pipe is slidably mounted, the exhaustpipe being movable with the cylinder.

In testimony whereof I affix .-ELZA R. DICKEY. [n 5.]
